Introduction In this series of articles I describe how you can write a Linux kernel module for an embedded Linux device. I begin with a straightforward “Hello World!” loadable kernel module (LKM) and work towards developing a module that can...

Introduction This post provides a straightforward set of “Hello World!” introductions to using CMake for building C++ projects. All steps are performed using Linux on the BeagleBone platform, but the instructions are relevant to most Linux platforms. The make utility and Makefiles...

This is what is keeping me busy at the moment… (very, very busy!). I have presently drafted 9 of the 14 chapters. This book on the BeagleBone is due for publication in Dec. 2014. A provisional description is available at: http://www.amazon.com/Exploring-BeagleBone-Techniques-Building-Embedded/dp/1118935128/ Derek....

Introduction I recently purchased the Digilent Analog Discovery and this is my first post on the tools that are available. I wrote this as a set of blog posts, but I have now replaced this with a full video on...

Introduction I recently purchased the Digilent Analog Discovery (Revision C). In this post I am looking at the Digital features, in particular the Pattern Generator and Logic Analyzer functionality. Test Circuit Setup For this test circuit I am going to use...

I have posted on how to do this exact thing using C++, so the first half is cut-and-pasted from Beaglebone: Controlling the on-board LEDs using C++ Introduction One of the first things you would like to do when you connect...

Introduction One of the first things you would like to do when you connect to the Beaglebone Black is see that you are having an impact on the hardware. In this short post I am going to look at how...

Before you start: First check if the distribution has changed to have a package installation of open java – Perform: [crayon-544e6faaef1f8168832857/] And see the output after you search for java [crayon-544e6faaef201679910846/] There are libraries and javascript tools, but no core...

Just a quick video guide to setting up Eclipse for both C++ and Java development under Windows. This is useful for one of the modules that I teach at DCU in Object-oriented Programming. It uses MinGW and CDT to allow...

Introduction In my last two blog entries I have discussed how you can stream video from embedded Linux devices such as the Beaglebone using FFMPEG/AVCONV, the V4L2 Capture program and the Logitech C920 USB Camera (with hardware MPEG4/H264). In these...

Introduction In a previous post, I described how you could set up the Beaglebone Black to capture video and process video using OpenCV with the Logitech C920 camera. In this post I am going to look at how you can...
